I'm doing cider in Normandie and I know that in the region selling apple juice with at least some percentage of bitter sweets and even bitters is done and successful, sometimes the juice is done by majority from it. However most of the producers would try to have acidic varieties by main percentage adding the bitter sweets by some tenths of percents. Personally I like apple juice both from acidic and partly bitter sweet or even bitter apples, the later I would be however very careful about. I do my cider in Cotentin and sometimes drinking the juice is quite an adventure, it is the region with most bitter ciders in France with exception with small part of Bretagne, can not remember name of that department. I offer my apple juice during tastings and I sell it (just starting in small quantities) to people which are from other countries than cider is consumed traditionally and they like the juice a lot. In my case I did it from apple mix quite traditional from Calvados region which would be roughly around 60% bitter sweets the rest some bitters, acidic and sweets.
I'd definitely recommend commercialization, I'm sure that you will find your clientele, it has something in it, well as cider from Normandie regions, polyphenols, more complex flavour ... By the way I did not filtered my product and did not use any additives, it is just pasteurized, it has been two years since I bottled the batch I'm talking about and it is still fine.
